Question

Intrinsic proteins are present on
1 ) both side of lipid bilayer
2) on outside of membrane
3) Inside of membrane
​

Answer 1

Intrinsic proteins are present inside the membrane.

Explanation:

• Intrinsic proteins are also known as integral proteins.

• These proteins are embedded inside the phospholipid bi layer.

• The main function of these intrinsic proteins of the plasma membrane, is to transport materials against the concentration gradient i.e form a lower           concentration to a higher concentration.

• The intrinsic proteins are involved in carrying material inside or outside the cells which cannot move through the cell on their own.
